Professional Applications & Engineering Value
These 10-32 UNF flat head Phillips screws are engineered to address common industrial fastening challenges, such as vibration loosening and material fatigue. Made from zinc-plated steel, they provide robust corrosion protection, making them ideal for machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The fine thread spacing and Class 2A thread fit ensure precise alignment and tight seals, reducing the need for rework. With a 100° countersink angle, they sit flush in pre-drilled holes, preventing snagging and improving safety in high-traffic areas. Their 60,000 PSI tensile strength and full threading distribute load evenly, offering reliable performance in industrial applications where durability and compliance are critical.
Specification Summary & Compliance
This product features a 10-32 UNF thread size with Class 2A thread fit for precise dimensional accuracy and smooth assembly. It complies with ASME B18.6.3 manufacturing standards, ensuring consistent quality and interchangeability. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance compliance for global industrial use.
